application filed. June 19, 1912. Serial No. 704,517.

To all whom it may concern.

Be it known that we, JoNAs W. Ans- WORTH, a citizen of the UnitedStates, resid ing at East Orange, State of New Jersey, and county ofEssex, and EDWARD L. AIKEN, a citizen of the United States, residing atOrange. county of Essex, and State ofNew Jersey, have invented certainnew and-useful Improvements in the Production of Sound-Records, of whichthe following is a description. a

Our invention relates to the production of sound records; and ourprincipal object is to provide a sound record having an improved labelor other means of identification. Our invention also contemplates theproduction of an improved matrix for forming the said record and alsoimproved processcs for making the record and the matrix. The productionof an improved matrix for forming said record, referredito above, isdescribed and claimed in copending application Serial No. 253,658 filedSeptember 11, 1918, entitled Matrices for producing sound records, andthe improved process for making sound records is described in copendingapplication Serial No. 253,652 filed September 11, 1918, entitledMethods of producing sound records, both of which copcnding applicationsare divisions of the present case. Other objects of our invention willappear in the following specification and appended claims:

In accordance with our invention, we form a matrix containing a reversedfacsimile of the design to be reproduced on the record, this designbeing in half tone. When the matrix has been obtained, the same ispressed into or against the record composition. "which is maintained ina plastic state during the pressing operation. The matrix preferablycontains a reversed facsimile of the sound record impressions as well asof the label; so that the record and the label can be impressed intotherecord tablet by a single operation. By means of a matrix formedaccording to oun invention, a label embodying the finest design may besatisfactorily impressed into the record tablet.

in order that the invention may be more clearly understood. reference ishereby made to the accompanying drawings in which Figures 1 to 4:inclusive are cross-sectional. views In practising the invention, anengraved copper cut lcontaining a reversed facsimile of the labelimpression is first made. This cut may be made by any of the well knownengraving processes, but is .preferably formed in half-tone by theprocess of photoengraving, a very fine screen, having preferably about400 lines per inch, being employed forproducing the half-tone efiect.This cut will have the parts which corre-' spond with the laces where nolight has passed through tl ie half'tone screen, such as the letters inthe label shown in the accompanying drawing, solidv and smooth, whilethe other portions, such as the background of the label shown, will becovered with minute depressions.corresponding to the light openings ofthe screen. The cut 1 should be left handed.

When the cut 1 has been obtained, the

same is pressed intoor against a member 2 formed of plastic composition.The composition of which the member 2 is formed is of such a nature asto be plastic at the temperature at which the impression is to he madethereon and to admit of the same being subsequently hardened. Theproduct which we prefer to employ for this purpose is fully described inan. application of-"Jonas W. Aylswo rth. Serial No. 543.238. filedFebruray 11, 1910, and entitled Phenolic condensation product and methodof preparing the same. upon which *United States Patent No. 1.020.593has been granted. It may consist of amiriture of fusible ingredientswhich are transformed by chemical action upon the application ofsuiiicient heat,

when it becomes cold. When the mixture of fusible ingredients abovereferred to is emously be formed of any material capable of beingrendered plastic so as to take a clear impression from the matrix.

wile we have described the preferred form of the invention, numerouschanges may be made in the specific disclosure herein made withoutdeparting from the spirit of the invention.

What we claim as new and desire to protect by Letters Patent is asfollows:

7 1. A .sound record formed of moldable record material and havin adesign molded in its surface, said design ing in half tone with at leastone hundred and fifty lines per inch, substantially as described. v

2. A sound record formed of moldable record material and having a designmolded in its surface, said design being in half tone with approximatelyfour hundred lines per inch, substantially as described.

3. A sound record having a surface por tion comprising'a hardenedinfusible phenolic condensation product containing" a plasticityingredient, whereby said surface portion becomes sufiiciently plasticwhen heated to take a clear impression from a die, said surface portionhaving a design in half tone molded therein, substantially as de,

scribed.

4. A sound record having a surface portion formed of a hardenedphenoliecondom sation product having a design molded therein, saiddesign being in half tonewith at least one hundred and fifty lines perinch, substantially as described. J

5. A sound record having a surface portion formed of a hardenedinfusible phenolic condensation product containing a plasticityingredient whereby the said surface portion becomes sufliciently plasticupon heating to take a clear impression from a die, the said surfaceportion having molded therein a design in half tone with at least onehundred and fifty lines per inch, substantially as described.

6. A sound record having a surface portion comprising a'hardenedinfusible phenolic condensation product containing a plasticityingredient, whereby the said sur face portion becomes suflicientlyplastic upon heating to take a clear impression from a die, the saidsurface portion having molded therein a design in half tone withapproximately four hundred lines per .inch, substantially as described.

7. A sound record having a surface portion formed of moldable recordmaterial and having a design molded its-surface, said design being inhalf tone with at least one hundred and fifty lines per inch and havingcoloring matter in its depressed portions, substantiallv as described.

This specification signed and witnessed this 17th day of June, 1912.
